Porous ferroelectric materials with conventional pore topologies have shown enhanced multifunctional performance. Here, we introduce a novel design and fabrication route to realize shell-based metamaterials, including spinodoids diamond shellulars, previously inaccessible multiphysical properties using customized piezoceramic additive manufacturing platform. The effective of spinodoid metamaterials are predicted by modified homogenization method. Assisted convolutional neural network, their...
In underground coal mines, uncontrolled accumulation of methane and fine dust often leads to serious incidents such as explosion. Therefore, dispersion in mines is closely monitored strictly regulated. Accordingly, significant efforts have been devoted study mines. this study, emission concentration are numerically investigated using a computational fluid dynamics (CFD) approach. Various possible scenarios mine configurations evaluated. The results indicate that the presence continuous miner...

Abstract Artificial ground freezing (AGF) has historically been used to stabilize underground structure. Numerical methods generally require high computational power be applicable in practice. Therefore, it is of interest develop accurate and reliable analytical frameworks for minimizing cost. This paper proposes a singular perturbation solution two-phase Stefan problem that describes outward solidification AGF. Specifically, the method separates two distinct temporal scales capture...
Sublimation drying is used in the process of semiconductor device manufacturing. However, solidification behavior mechanics sublimation agents on substrates has not been clarified. Therefore, properties solidified films within substrate surfaces can become nonuniform, leading to their collapse. This study aimed analyze interface growth during cooling and a water/ice system as basic case clarify dynamic mechanism liquid Si substrates. The was captured video at different rates. recorded...
With the ever-increasing engineering and biological applications of rapid droplet solidification on superhydrophobic surfaces, developing accurate dendritic growth models has become vital at lower bulk temperatures. In addition to thermal diffusion, interface kinetics curvature effects non-negligible such low temperatures thus should be taken into account. this study, we present a novel crystal model coupled with heterogeneous nucleation investigate dynamics recalescence stage during...
Energy conversion efficiency of a thermo photo voltaic (TPV) system strongly depends on the wall temperature and its uniformity. Therefore, improving heat transfer characteristics these systems is focus many recent studies. Significant efforts have been devoted to investigate flame stabilization enhancement for straight channels; planar circular. However, investigation impact curvature flow reacting limited, implying that more studies are required. This study explores effect transfer,...
The interest in the underground seasonal thermal energy storage system as a renewable option for residential applications increases recent decades. system, basically, uses shallow ground an reservoir that absorbs and release heat hot cold seasons, respectively. This paper presents, by means of mathematical model, novel open-loop configuration using network bayonet tube exchangers. A validated two-dimensional multiphase model describing mass, momentum conjugate transfer between surrounding...
In heat exchanger application, working fluid inside the tubes is subjected to considerable temperature changes. order improve transfer performance, various strategies are proposed and evaluated; one of them application coiled tubes. Coiled have been used widely in mainly due presence secondary flow which enhances considerably. This study addresses performance three configurations with square cross-section, i.e. in-plane, helical conical tubes, large difference. Their numerically evaluated...
